Electrode Potentials in Fused Systems X. Measurement of Cation Concentration in Molten Salts Using Glass Membrane Electr...
Published in Journal of Research of the National Bureau of Standards. Section A, Physics and Chemistry
A potentiometric method utilizing glass membrane reference electrodes in a concentration cell for the continuous measurement in situ of molten salt composition is presented. Relevant data for the AgCl-NaCl, AgBr-NaBr, and Ag2SO4-Na2SO4 systems are given. Using cells of the type M 1 | M 1 A ( a R ) , M 2 A ( a R ′ ) | glass | M 1 A ( a 2 ) , M 2 A (...
Balances à quartz résonnants de grande sensibilité fonctionnant en ultravide et à très basse température : Application à...
Nous décrivons un dispositif expérimental destiné à l'étude des interactions entre les gaz et les solides à très basse température. Le système de mesure proprement dit est constitué de six quartz résonnants. Cinq quartz très sensibles à la masse déposée sur leurs électrodes, permettent de mesurer la variation du nombre d'atomes condensés ; le sixiè...
A discharge coordinate detection system
A device is described which makes it possible to record the coordinates of the spots of recurrent electrical discharges. These discharges are produced between electrodes which are separated by a small gap filled with an insulating liquid. Conditioning effects occurring in the liquid dielectric are presumed to modify the discharge pattern. An initia...
Etude expérimentale des réactions de transfert de charges sur électrodes semiconductrices : oxydoréduction des anions co...
Ce travail concerne l'étude expérimentale des réactions de transfert de charges à l'interface électrode semiconductrice électrolyte aqueux. La voltamétrie cyclique dans le noir et sous éclairement a permis d'étudier les réactions d'oxydoréduction des anions complexes Fe(CN)3-/4-6 et Co(CN)3-/4-6 sur les électrodes de tellurure de zinc et de cadmium...
An Interlaboratory Test of pH Measurements in Rainwater
Published in Journal of Research of the National Bureau of Standards
An interlaboratory test of pH measurements in rainwater has been conducted. Various types of electrodes and junction materials were used in this test. The results of this exercise verify that there are significant differences in the pH values of low ionic strength solutions reported by various laboratories. Other work suggests that these difference...
Nouvelle technique d'hyperthermie interstitielle à 27 MHz
International audience
Practical interstitial method of heating operating at 27.12 MHz
A practical interstitial capacitive method of heating using thin flexible coated electrodes operating at 27.12 MHz is described. Advantages compared to classical interstitial methods are: uniform heating, control of the inserted length, compatibility with curie therapy, simplicity and low cost. The electrode geometry could be designed according to ...
A multichannel interstitial capacitive hyperthermia system as an adjunct to brachytherapy
An alternative interstitial hyperthermia system using thin flexible electrode wires operating at 27.12 MHz has been developed, and an 8-channel apparatus has been evaluated. Its major benefit is its potentializing effect, which is obtained without affecting radiation therapy techniques. It is possible to match the electrode to any kind of catheter ...
